* Follow protocol grammar fix `GCPhrase -> GCPhase`

* Fix doc.

Fix potential NPE in OAL string match and a bug when right-hand-side variable includes double quotes (#8234)

The ES persistence execution is now asynchronous and the execution
latency only counts the time to insert the requests into the bulk
processor, instead of the time after the requests are flushed into the
storage, this patch fixes that issue.

There is the same issue in prepare latency but that needs more changes
so I'll leave it to another pull request.

Optimize metrics of minute dimensionality persistence, don't save metric of being default value. (#8066)

Optimize metrics of minute dimensionality persistence.
- The value of metrics, which has declaration of the default value and current value equals the default value logically, the whole row wouldn't be pushed into database.
- Add self-observability `metrics_persistence_skipped` metric to measure the number of skipped metrics.
- SLA(percent function), Apdex, AvgLong(MAL mostly) metrics are mostly optimized because of this. Such as a full-failing error(0% successful rate) and unhealthy(apdex=0) are not costing the storage.
- Hour/Day dimensionalities metrics are not changed, as they cover long duration.
- Fix `max` function in OAL doesn't support negative long.

Add a GraphQL query to get OAP version, display OAP version in startup message and error logs (#8004)

* Support `!= null` in OAL engine.
* Add `Message Queue Consuming Count` metric for MQ consuming service and endpoint.
* Add `Message Queue Avg Consuming Latency` metric for MQ consuming service and endpoint.
* Document with a new menu in the `tracing` catalog is added

* fix: Fix MultiScopesAnalysisListener#setPublicAttrs log warn frequently. #6562

1. Rename current STATUS_CODE to HTTP_RESPONSE_STATUS_CODE, real tag key should be http.status_code.
2. Add a new string tag RPC_RESPONSE_STATUS_CODE to hold all string type value tag. The key is `rpc.status_code`.
3. At the backend, keep responseCode for HTTP_RESPONSE_STATUS_CODE tag, but add @Deprecated. Also, add httpResponseStatusCode(a duplicate of responseCode) and rpcStatusCode(for RPC_RESPONSE_STATUS_CODE) fields for OAL.

* Modify `Tags.STATUS_CODE` field name to `Tags.HTTP_RESPONSE_STATUS_CODE` and type from `StringTag` to `IntegerTag`, add `Tags.RPC_RESPONSE_STATUS_CODE` field to hold rpc response code value.

* Add `rpcStatusCode` for `rpc.status_code` tag in the OAL objects. The `responseCode` field is marked as deprecated and replaced by `httpResponseStatusCode` field. 

* Tag `status_code` is still supported in the backend for forward compatbility. Will be removed one year later.
